[mrtg] Cisco AS5300 modem monitoring

I hope that someone might be able to help.

I have a Cisco AS5300 router and would like to use MRTG to monitor the modem
call durations.  The router has 120 modems.  They are numbered 1/0 through
to 1/59 and then 2/0 to 2/59.

Cisco have confirmed to me that modem 1/1 would have an OID ending in 1.1
and 1/2 ends in 1.2 etc, etc...

My MRTG server runs on Windows NT.  I am able to do snmpwalk (using snmputil
- same as snmpwalk) - I can get a response from the router with the call
durations of users.  This output is below:

C:\>snmputil get community .
Variable = .iso.org.dod.internet.private.enterprises.
Value    = TimeTicks - 39130

(I have changed my router's IP to and also changed the community
name to "community")

That's the background....can anyone advise why my graph shows a flat line,
which never changes, and also doesn't reflect the actual connect speeds.
In my log file all I get is zero's.

I suspect the problem is the MaxBytes option but I cant find anything in the
FAQ to help.

MRTG is running ok for other routers.

Can anyone please help ??  Many thanks in advance.
